Leaked Pentagon data exposes US intelligence's knowledge of Chinese spy balloons.

Leaked top-secret data from the Pentagon reveals that US intelligence agencies were aware of at least four Chinese spy balloons, including the one that attracted national attention earlier this year. The documents also reveal a lack of "strong senior" oversight of the balloon surveillance program and suggest that the balloons are named after notorious criminals. Republicans have blamed the Biden administration for delaying the shooting down of the balloon, allowing China to continue spying on the US. NBC reported that the balloon was still able to gather intelligence from sensitive military sites despite the administration's efforts to block it.
